Chapter 14, Problem 112E

Interpretation Introduction

Interpretation:

The pH of the $\text{ HCl}$ solution is to be calculated after the addition of calcium metal.

Concept Introduction: Strong acids ionize completely in water to form an ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}$ ion.

The pH of the solution is defined as

$\text{pH}=-\text{log}\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$

Molarity of a solution is defined as

$\text{Molarity}\left(\text{M}\right)=\frac{\text{moles solute}}{\text{L solution}}$

The moles $\left(n\right)$ are defined as the ratio of mass to the molar mass.

$n=\frac{\text{Mass}}{\text{Molar mass}}$
